We have a concept of infinity, but perhaps it's a misconception. Maybe things are finite and in our fantasy we can go to infinity, but in reality it doesn't work that way.
Things often look continuous because they are composed of such minuscule units and in our imagination we can take a quantity of gold and subdivide it into smaller quantities of gold and we can repeat that step infinitely often.
But we know that we will reach atoms of gold eventually and we can not split them up into smaller quantities of gold.
The same might be true for space and time itself. So it would be premature to claim that infinity exists or doesn't exist while we still
have no comprehensive theory that accounts for everything (space, time, information, energy, matter).
